(NOTE: That mochi_manage will be added only if you first time activate the mochi plugin. If you already activated the plugin then temporarly copy this piece of code to another function which will run next time then remove)

change this in function mochi_add_games():

$post[‘post_author’] = get_the_author_id();

Then I added new users who should be allow to manage mochi plugin, I set them role to ‘Editor’ the with Role Manager I added permission: ‘Manage_mochi’
